You have 7 times as many nickels
as pennies. You have 16 nickels
and pennies altogether. How
much money do you have in all?
Answers
The total money you have is $40.14.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
There are 7 times as many nickels as pennies
Let there are n nickles and p pennies.
⇒ p = 7n
Now, there are 16 nickels and pennies altogether
⇒ p + n = 16
Put p = 7n we get,
⇒ 7n + n = 16
⇒ 8n = 16
⇒ n = 16/8
⇒ n = 2
Therefore, p = 7*2
⇒ p = 14
Thus there 14 pennies and 2 nickels.
Now, since 1 penny = 0.01 dollars
and 1 nickel = 20 dollars
⇒ 14 pennies = 14*0.01 dollars = 0.14 dollar
and, 2 nickel = 2*20 dollars = 40 dollars
So, Total money = $40 + $0.14
⇒ Total money = $40.14
Thus, the total money you have is $40.14.

Which equation represents a line with a slope of -8 and
a y-intercept of 4?
A y = -8x+4
B y = -4x+8
C y = - 8x-4
D y = 8x+4
Answers
Answer: A. y = -8x + 4 because the slope goes in front with the x (-8x) and the y intercept is after the slope (4)
I = $141.60; P = $590; t = 6 years
Find the rate
Answers
Using the simple interest formula:
I = P • r • t
Divide both sides by P•t to isolate r:
I / P • t = (P • r • t)/ P • t
I / P • t = r
Now that we have the formula for r, substitute the given values into the equation:
r = $141.60/($590 • 6)
r = 0.04 or 4%
Therefore, the interest rate is 4%

Two mechanics worked on a car. The first mechanic worked for 5 hours, and the second mechanic worked for 15 hours. Together they charged $1650. What was the rate charged per hour by each mechanic if the sum of the two rates was $140 per hour?
Answers
y = rate of mechanic who worked 15 hours
Then
x + y = 235
5x + 15y = 2375
Just solve these 2 equations above for x and y.
x + y = 235 ⇒ x = 235 - y
Substitute into second equation to find y.
5(235 - y) + 15y = 2375
1175 - 5y + 15y = 2375
10y = 1200
y = 1200/10 = 120
x = 235 - y = 235 - 120 = 115
The mechanic who worked 5 hours charged $115 per hour, the one who worked 15 hours charged $120 per hour.

The solution of a linear equation with rational coefficients is a rational number. A. Always B. Never C. Sometimes
Answers
9514 1404 393
Answer:
A. Always
Step-by-step explanation:
A linear equation with rational coefficients can be written in the form ...
ax +b = 0
The solution for the variable x is ...
x = -b/a
The problem statement tells us that 'a' and 'b' are rational numbers. Assuming there is a solution (a≠0), that solution is the ratio of rational numbers, hence must always be rational.

If the area of this rectangle is 30cm square what would the missing side be?
Answers
A = L • W [Area if Rectangle Formula]
A = 30cm^2 [Given]
(30) = (6) • W [Substitution Property of
Equality]
30 / 6 = 6 • W / 6 [Division Property of
Equality]
5 = W [Definition of Equality]
W = 5 [Symmetric P.O.E]
Therefore, the width of this rectangle is 5.
We can check this because A = 6 • 5 = 30cm^2
